Sylvia's Tomb, PLEASE HELP!

Hey! I am in The Necropolis at the point that I have to find Slyvia in the tomb and use the crystal. I need help. My other friend tried but he tells me he has to leave after the first floor. I got another friend that just stood there the whole battle and took action the time I HAD TO LEAVE! My friend that is on the same quest is not on as often as me. Please come along and do this quest together.
